Abstract

A setting method includes determining a specification of a chiller unit of an air-conditioning machine room based on a cooling load of a building. The specification of the chiller unit includes an inlet and outlet specification and a pipe diameter. The method further includes determining a specification of a water pump of the air-conditioning machine room based on a preset system water flow, and determining a valve member of the air-conditioning machine room. A specification of the valve member matches the pipe diameter. The method also includes plotting the chiller unit, the water pump, and the valve member on a design layout, and connecting the chiller unit, the water pump, and the valve member The chiller unit, the water pump, and the valve member are proportionally scaled according to the specification of the chiller unit, the specification of the water pump, and the specification of the valve member.
